Excellent hardening effect in lead-free piezoceramics by embedding local Cu-doped defect dipoles in phase boundary engineering
Phase structure
X-ray diffraction (XRD) patterns show that all samples have a typical perovskite structure. At high doping content, a minor CuO phase is observed (Supplementary Fig. 1), indicating that Cu2+ ions have entered into the lattice of…

Simulating two-dimensional lattice gauge theories on a qudit quantum computer
Realizing controlled rotations in qudits
We encoded each qudit in Zeeman states of trapped 40Ca+ ions and manipulated their quantum state by sequences of laser pulses. Doppler cooling and state detection were performed by driving the short-lived…

This Tiny Particle is Redefining Our View of the Atomic Nucleus
University of Queensland scientists have cracked a long-standing puzzle in nuclear physics, showing that nuclear polarization, once thought to hinder experiments with muonic atoms, has a much smaller effect than expected. This surprising result…

The expanding Universe — do ongoing tensions leave room for new physics?
On 1 January 1925, US astronomer Henry Norris Russell made a startling announcement to the American Astronomical Society in Washington DC: observations by fellow astronomer Edwin Hubble showed that the Milky Way did not encompass the cosmos, and…

Vanadium dioxide enabled polarization insensitive tunable broadband terahertz metamaterial absorber
The simulation results of the absorption curve, derived from optimized structural parameters, are presented in Fig. 2, with the conductivity of VO2 set at 200,000 S/m. The figure illustrates that the absorber achieves a broadband absorption…

Sampling reduced density matrix to extract fine levels of entanglement spectrum and restore entanglement Hamiltonian
Method
In a quantum many-body system, the ES of a subsystem (entangling region) A with the rest of the system B (environment) is constructed via the RDM. The RDM is defined as the partial trace of the total density matrix ρ over a complete basis…
